iTerm2
iTerm2 is a replacement for Terminal and the successor to iTerm. It works on Macs with macOS 10.14 or newer. iTerm2 brings the terminal into the modern age with features you never knew you always wanted. iTerm2 has a lot of features. Every conceivable desire a terminal user might have has been foreseen and solved. And these are just the main attractions! Divide a tab up into multiple panes, each one showing a different session. You can slice vertically and horizontally and create any number of panes in any imaginable arrangement. Register a hotkey that brings iTerm2 to the foreground when you're in another application. A terminal is always a keypress away. You can choose to have the hotkey open a dedicated window. This gives you an always-available terminal at your fingertips. iTerm2 comes with a robust find-on-page feature. The UI stays out of the way. All matches are immediately highlighted. Even regular expression support is offered!

TmuxAI
TmuxAI is an intelligent terminal assistant that lives inside your tmux sessions. Unlike other CLI AI tools, TmuxAI observes and understands the content of your tmux panes, providing assistance without requiring you to change your workflow or interrupt your terminal sessions.
Think of TmuxAI as a pair programmer that sits beside you, watching your terminal environment exactly as you see it. It can understand what you're working on across multiple panes, help solve problems and execute commands on your behalf in a dedicated execution pane.
TmuxAI's design philosophy mirrors the way humans collaborate at the terminal. Just as a colleague sitting next to you would observe your screen, understand context from what's visible, and help accordingly, TmuxAI:
Observes: Reads the visible content in all your panes
Communicates: Uses a dedicated chat pane for interaction
Acts: Can execute commands in a separate execution pane (with your permission)

WezTerm
WezTerm is a high-performance, cross-platform terminal emulator and multiplexer built in Rust that delivers GPU-accelerated rendering, including ligatures, color emoji, true color, dynamic color schemes, and hyperlinks, and modern windowing controls such as panes, tabs, and multiple windows on both local and remote hosts. Its single-process multiplexer provides scrollback, searchable history, mouse integration, Quick Select mode for rapid selection, Copy mode, shell integration, support for the iTerm image protocol, SSH connectivity, serial ports, Arduino devices, and workspace/session management via Lua-configurable scripts. Configuration is handled through a wezterm.lua file with hot-reload support, while a rich command-line interface (wezterm cli) lets you spawn programs, manipulate tabs and panes, and set domains. WezTerm adheres to ECMA-48 and xterm conventions for full ANSI/ISO compliance and offers native UI integration using platform-specific APIs.

Herdr
Herdr is a terminal-based runtime and multiplexer for developers who run AI coding agents, shells, tests, and other command-line tools. It organizes work into workspaces, tabs, and panes managed by a background server, so processes can keep running when a client disconnects. Users can reattach locally or connect to Herdr on other machines over SSH. The software detects supported coding agents and displays whether they are working, blocked, idle, or done; integrations can preserve native agent sessions after a server restart. Its CLI and local socket API let scripts and agents inspect sessions, manage panes, start or prompt agents, and wait for state changes. Developers can configure keybindings and themes and extend workflows with local executable plugins. Herdr is installed on macOS, Linux, or Windows and is released under the Apache 2.0 license.
